What is a Astron power supply used for?
What is a Astron power supply used for?
The RS-12A is a 300 Watt DC Power Supply from Astron. Supplies DC Voltage and Current to test, design, and troubleshoot electric and electronic circuits. Applications include Burn In, QA, ATE, Research, Design, and Education to name a few.
How do you ground an Astron power supply?
Your Astron Power Supply is Grounded via the NEMA 5-15R (your AC wall outlet), per NEC and UL. The NEMA 5-15P (plug) has a 3/16-inch (4.8 mm) diameter Round or U-shaped GROUND PIN. this pin is 1/8-inch (3.2 mm) longer than the power blades (so the device is grounded before the power is connected).
Where are Astron power supplies made?
the USA
Since 1976, Astron Corporation has been a premier manufacturer of Linear Power Supplies. Made in the USA, our Linear Power Supplies have reliably served Commercial and Ham operators alike for over forty years.
What is a Astron RS 20A?
Product description. The Astron RS series are continuous duty power supplies designed to withstand the rigors of heavy-duty or industrial use. RS-20A has a continous 16 amp rating with a 20 amp intermittent duty rating @ 13.8VDC. (50% duty cycle: 5 min on / 5 min.
What is the difference between a switching and linear power supply?
Linear power supplies deliver DC by passing the primary AC voltage through a transformer and then filtering it to remove the AC component. Switching power supplies feature higher efficiencies, lighter weight, longer hold up times, and the ability to handle wider input voltage ranges.
Which is better switching or linear power supply?
Switching power supplies feature higher efficiencies, lighter weight, longer hold up times, and the ability to handle wider input voltage ranges. Linear power supplies are usually less expensive, but are limited in capability and tend to be larger in physical size.
What is the purpose of a switching power supply?
What is a Switching Power Supply? Switching power supplies are designed for high efficiency and small size. They incorporate a switching regulator to convert electrical power efficiently. Switching DC power supplies regulate the output voltage through a process called pulse width modulation (PWM).
What is the advantage of a switching power supply?
The main advantage of the switching power supply is greater efficiency (up to 96%) than linear regulators because the switching transistor dissipates little power when acting as a switch.
What are the 2 drawbacks of linear power supply?
In summary, the disadvantages of linear power supplies are higher heat loss, a larger size, and being less efficient in comparison to the SMPS. The primary issue attributed to the linear power supply’s inadequacy in high-power applications is its size and weight.
Which is better linear or switching power supply?
A switching power supply has greater efficiency than linear regulators because the switching transistor dissipates little power when acting as a switch. However, this switching can generate noise which can be lowered by filtering.
Is a switching power supply regulated?
A switch mode power supply regulates an output voltage with pulse width modulation (PWM). Any regulation required to keep the output voltage consistent is handled by adjusting the pulse width of the high-frequency waveform.
What is the difference between a switching and regulated power supply?
There are two topologies to consider for this goal, linear regulated and switch mode power supplies. Linear regulated is ideal for applications that require low noise, whereas switching power supplies are better suited for handheld devices where battery life and efficiency is important.
How to repair Astron 13.8V linear power supplies?
Some may only be a few words long, but it is all very important, and many useful hints, clues, and tidbits will be found if you read it a few times. The most common issues will be covered. It’s up to you to test every component, which may include unsoldering one or both leads of each part to do so.
Are there any issues with Astron power supply?
The most common issues will be covered. It’s up to you to test every component, which may include unsoldering one or both leads of each part to do so. Trying to measure some resistors while installed in the supply may lead to inaccurate readings.
What kind of test is needed for Astron linear power supply?
There are a few pieces of test equipment that are very handy for fixing Astron linear power supplies. The first is a good old volt-ohm-milliammeter (VOM). Almost any one will do, but the industry-standard Simpson 260 or 270 series is probably the most well known. You’ll use this meter to measure voltages and resistances.
Is there a bleeder resistor in an Astron power supply?
There is no bleeder resistor in any of the Astron power supplies (unless you add one yourself). This article assumes that the reader is familiar with simple AC and DC circuits and most electronic components and knows how to use a voltmeter and an ohmmeter. Parts can fail in odd ways.
